What is the function of the microtubules in an eukaryotic cell

Microtubules are hollow, cylindrical structures that are essential for various cellular functions in eukaryotic cells. They are composed of tubulin protein subunits and play a crucial role in maintaining cell shape, providing structural support, and transporting materials within the cell.

Functions of Microtubules:

Cell Shape and Support: Microtubules contribute to the cell's overall shape and rigidity by forming a dynamic framework within the cytoplasm.
Mitotic Spindle Formation: During cell division, microtubules organize into a mitotic spindle, which segregates chromosomes to ensure equal distribution between daughter cells.
Intracellular Transport: Microtubules act as tracks along which motor proteins, such as kinesins and dyneins, transport organelles, vesicles, and other cellular components.
Cilia and Flagella: Microtubules are the primary structural component of cilia and flagella, which are responsible for cell movement.
Signal Transduction: Microtubules have been implicated in various signaling pathways, including the activation of transcription factors and the regulation of cell growth.
